I am very satisfied with the buying experience, the product, and say enough good things about the customer service. I bought their Extend-A-Slide, a device for copying slides. The website was helpful in learning about the issues involved. When I needed a part replaced to make the product work better, the replacement was mailed the next day with a postage paid return envelope. No cost and no questions. The owner, Phil, must carry a "Blackberry" everywhere. I have emailed questions to him on a Sunday, and gotten a response within minutes.
